ASTM/AISI Standard Alloy Round Bar AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint.

AISI 4130 steel is a low alloy steel that is used in structural designs that may be found in applications such as aircraft engine mounts or welded tubing. It is well known for its ease of welding and ability to harden in commercial applications. It is commonly referred to as chromium-molybdenum steel.

1. Use solid 45# carbon or 40Cr steel as raw material. 2. Tensile Strenth is more than 540MPa, 630MPa and 720MPa. The standard rebar threaded coupler is suitable for connecting two bars of the same diameter, where one bar can be rotated. It comprises an internally threaded sleeve with two right hand threads which are tapered towards the middle of the coupler. The bar ends are square cut and thread is onto the bar. A nominal allowance of +25mm should be allowed per threaded bar end for square cutting the bar end. The couplers are generally torqued onto the reinforcing bar in the bar threading shop, the internal threads protected by plastic end caps. The threaded ends of the continuation bar are protected by plastic thread protectors.

Glass Balustrade Systems Glass balustrade systems are impressive and represent a flexible modern design solution. Frameless glass balustrades perfectly comply with a popular minimalist aesthetics. We will use the highest-quality hardware compliant with building codes. Our glass balustrade systems contribute to creating a clean, comfort and unobstructed view. It is commonly made with tempered monolithic glass or laminated glass, which is not only safe for the railing use but also allows natural light to flow into the room. The enhanced natural lighting results in better aesthetics and elimination of shadows, and additionally reduces artificial lighting demands, helping cut both electricity bills and carbon emissions.

Balcony Glass Railing North Glass' glass balcony railing systems can be used for any staircase, deck, pool, guardrail or other suitable application where a safety railing, fence or handrail is required. North Glass offers installers a cleaner, easier way to install tempered glass panels into our structural shoe mouldings - which look smooth due to the streamlined, post-free design. North Glass has revolutionised the dry glazed shoe moulding system by combining maximum glass tilt adjustability with an intuitive locking mechanism, dramatically increasing installation speed and ensuring precise glass alignment. The North Glass glass balcony railinge is our post mounted design solution, offering affordable glass balustrades that are extremely easy to install with endless customisable options.

The North Glass balustrade range is our post mounted design solution, offering affordable glass balustrades that are extremely easy to install with endless customisable options. North Glass is pleased to announce the arrival of our glass balustrade system and all-glass fabrication facility. Glass balustrades are the first choice for landscape protection and security. In outdoor applications, glass is very effective as a windbreaker, making it very popular in waterfront properties. While it helps to block the more violent winds, the small gaps between the glass and the posts and handrails allow you to enjoy the breeze. The transparent panels give the illusion of an invisible balustrade when the natural view is through. The treated glass requires little maintenance except for occasional cleaning with soap and water or other glass cleaners.
